Five new billion-dollar weather and climate disasters were confirmed in April 2024, including three severe storm events that impacted the central, southern and eastern U.S. in mid-February and early April. There were also two winter storms that impacted the northwest and central U.S. in mid-January.
There have been seven confirmed weather and climate disaster events this year, each with losses exceeding $1 billion. These disasters consisted of five severe storm events and two winter storms.
The U.S. has sustained 383 separate weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2024). The total cost of these 383 events exceeds $2.720 trillion.
A spring storm brought rain, heavy snow, damaging winds and thunderstorms across much of the Great Lakes on April 2, knocking out power to over 100,000 people across the region during the height of the storm.
Severe weather across the Southeast produced a hailstorm that caused over $5 million in damages in Rock Hill, SC on April 20.
On April 26, severe weather across the central Plains resulted in the National Weather Service in Omaha, Nebraska issuing 48 tornado warnings—the most the office has ever issued in a single day.
According to the April 30 U.S. Drought Monitor report, about 17% of the contiguous U.S. was in drought, down about 1% from the beginning of April.

Drought contracted or was reduced in intensity across much of the central Mississippi Valley and Upper Midwest, and in parts of the Southwest, northern Plains, Hawaii and Puerto Rico.
Above-average temperatures are favored to impact areas from the southern Plains to the East Coast in May while above-average precipitation is likely to occur from much of the central Plains to the Mid-Atlantic and parts of the Upper Midwest. Drought is likely to persist along portions of the Northern Tier, the Southwest and Hawaii.

Significant wildland fire potential for May is above normal across the Hawaiian Islands and in portions of the Southwest and Florida Peninsula. For additional information on wildland fire potential, visit the National Interagency Fire Center’s One-Month Wildland Fire Outlook.
